[dotnet-sdk-10.0.100-alpha.1.25057.15] InternetTest crashes due to exception " The requested protocol has not been configured into the system, or no implementation for it exists".

[Junjun-zhao]

Description

When onboarding the 3rd party application and running against with dotnet-sdk-10.0.100-alpha.1.25057.15, the app crashes with error: The requested protocol has not been configured into the system, or no implementation for it exists. After investigating, we found this issue starts from dotnet-sdk-9.0.100-preview.4.24267.66 build.

Application Name: InternetTest
OS： Windows 10 22H2
CPU: X64
.NET Build Number: dotnet-sdk-10.0.100-alpha.1.25057.15
App & Source Location checking at: https://devdiv.visualstudio.com/DevDiv/_workitems/edit/2346272
Github Link: https://github.com/Leo-Corporation/InternetTest

Reproduction Steps

App Repro Steps:

1. Launch "Desktop\InternetTest\App\InternetTest\InternetTest.exe”.
2. Click “Skip” if a window displays.
3. Click “WiFi Networks”.
4. Click “Network adapters”.

Expected Result:
Networks show on screen.

Actual Result:
Pop up window with error:
The requested protocol has not been configured into the system, or no implementation for it exists.

Minimal Repro Steps (Demo attached:ConsoleDemo (4).zip):
Please refer to the Repro machine from Devdiv bug

1. Create a default 8.0 console project.
2. Copy the following code to Program.cs.

using System.Net.NetworkInformation;
NetworkInterface[] ns = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface n in ns)
{
    int Mtu = n.GetIPProperties().GetIPv4Properties().Mtu;
}

3. Build the project.
4. Change the runtime.config file to let the app run against with dotnet-sdk-10.0.100-alpha.1.25057.15:

"frameworks": [
      {
        "name": "Microsoft.NETCore.App",
        "version": "10.0.0-alpha.1.25052.4"
      }
    ]

5. Launch the app.

Expected behavior

All NetworkInterfaces passed.

Actual behavior

Actual Result:
Some NetworkInterfaces fail with error:

Other information

Findings:
When debugging into the app source code, we found that, NetworkInterface.GetAllNetworkInterfaces() returns 2 Network Interfaces with dotnet-sdk-9.0.100-preview.3.24204.13 and before. Started from 9.0.100-preview.4.24267.66, it returns 11 Network Interfaces and some of them will throw "The requested protocol has not been configured into the system, or no implementation for it exists" exception when getting its GetIPv4Properties().Mtu property.
The NetworkInterface count that returned will be different on different machines. But the returned count on machines that installed 9.0.100-preview.4.24267.66 and later version is greater than the machines installed with previous version.
And We found following network interfaces come will cause the exception on our test machines:

This is due to #100824 / #102900.

E.g. on my machine this throws for vSwitch (Default Switch)-Hyper-V Virtual Switch Extension Filter-0000 which we wouldn't return from GetAllNetworkInterfaces before 9.0.

The GetIPProperties for it appears empty, GetIPv4Properties throws.

@wfurt is this the expected behavior here?

[wfurt]

I don't think it should throw. I feel we still may keep #100824 to show all the OS interfaces but we should handle cases when IP is not configured gracefully.

[Junjun-zhao]

Hi @wfurt , Thanks for looking into this issue. Could you please confirm if this is a blocker for .NET 10 Preview1?

[wfurt]

I think we should investigate but I personally would not see it as blocking preview.

[CancanTang]

Hi @wfurt ,Is there any update on this issue? What is the plan or schedule for addressing it?

[antonfirsov]

Couple of thoughts:

1. I think the expectation that GetIPv4Properties() should always succeed with a valid IPv4InterfaceProperties object for all interfaces is not realistic. For example, disabled adapters (the ones the original issue asked to be included) can't have any meaningful data there. I think the appcompat test should be changed allowing NetworkInformationException to be thrown from GetIPv4Properties(). It is a documented behavior.

2. We may consider adding API for querying whether an interface is IPv4 or IPv6-enabled, so users don't have to catch an exception but ask upfront. Eg. we could introduce new bool properties on IPInterfaceProperties. Scrap this, we have NetworkInterface.Supports(NetworkInterfaceComponent.IPv4).

3. On my machine GetAllNetworkInterfaces() lists 9 devices on .NET 8, but with GAA_FLAG_INCLUDE_ALL_INTERFACES on .NET 9 there are 70 "interfaces" with most of them being filter drivers installed by tools like Hyper-V or NPCAP. Personally, I think this as a major inconvenience (or even a bug) and if there is no better way to fetch disabled devices, I would even consider reverting Changed GetNetworkInterfaces method to to retrieve information related to all interfaces #100824 / fix NetworkInterface properties on Windows #102900.

@wfurt thoughts?

@CancanTang @Junjun-zhao we discussed this offline with the team, and concluded that the InternetTest application has a bug, see Leo-Corporation/InternetTest#651.

The exception is an expected behavior GetIPv4Properties() should be always preceded by a capability check:

using System.Net.NetworkInformation;
NetworkInterface[] ns = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface n in ns)
{
    if (n.Supports(NetworkInterfaceComponent.IPv4))
    {
        int mtu = n.GetIPProperties().GetIPv4Properties().Mtu;
        Console.WriteLine(mtu);
    }
    else
    {
        // IPv4 is not supported or disabled for this device, there is no valid MTU value.
    }
}
